The decay rate of standing deadwood, i.e., of snags, is slower than that of downed deadwood in contact with the forest floor. We agree with Dr. Anger’s opinion that this may be an important reason why clear age differences in the decay classes 1 – 3 are missing. Some snags fall earlier others later. This overshadows a clear age trend in decay. If the rate at which snags of larch fall down on th...

Reassessing the human immunodeficiency virus type 1 life cycle through age-structured modeling: life span of infected cells, viral generation time, and basic reproductive number, R0.

The rapid decay of the viral load after drug treatment in patients infected with human immunodeficiency virus type 1 (HIV-1) has been shown to result from the rapid loss of infected cells due to their high turnover, with a generation time of around 1 to 2 days. Traditionally, viral decay dynamics after drug treatment is investigated using models of differential equations in which both the death...

Qualifying and Quantifying the Rate of Decomposition in the Delaware River Valley Region

Human decompositional changes and the post-mortem interval (PMI) required to produce those effects have been demonstrated to vary tremendously based on environmental conditions specific to the region in which decomposition is taking place. Studies to that effect have been conducted in select areas throughout the country, but have yet to be undertaken in southeastern Pennsylvania, New Jersey, an...

Time since death and decay rate constants of Norway spruce and European larch deadwood in subalpine forests determined using dendrochronology and radiocarbon dating

Due to the large size (e.g. sections of tree trunks) and highly heterogeneous spatial distribution of deadwood, the timescales involved in the coarse woody debris (CWD) decay of Picea abies (L.) Karst. and Larix decidua Mill. in Alpine forests are largely unknown. We investigated the CWD decay dynamics in an Alpine valley in Italy using the chronosequence approach and the five-decay class syste...
